python - 如何将 python 脚本连接到 PyQt5 中的按钮？
问题描述
我试图为桌面应用程序创建一个 GUI，并且从一个窗口我想将其中一个按钮连接到另一个脚本，实际上它工作正常，除了负责在 update_window.py 中处理第二个窗口“exit_popup_message”的函数，所以我成功运行第一个文件并单击“更新用户”按钮，它成功运行第二个窗口，但是每当我在第二个窗口中单击退出时，它就会崩溃并出现此错误：
进程以退出代码 -1073740791 (0xC0000409) 结束

解决方案
每当有疑问时，我建议您尝试从终端/提示符运行您的程序，因为 IDE 倾向于隐藏错误的完整回溯。
在这种情况下，它将如下所示：
Traceback (most recent call last):
File "/tmp/update_window.py", line 250, in exit_popup_message
UpdatePage.close()
NameError: name 'UpdatePage' is not defined
这是由两个问题引起的，一个是严格的程序问题，另一个是概念问题。
当您运行update_window.py文件时，if __name__语句中的块被执行（因为__name__is '__main__'）并且从那时UpdatePage起存在，它可以正常工作。请注意，这UpdatePage是一个全局变量，应始终避免使用全局变量。
相反，当您运行该user_info.py文件时，只会执行该文件，而if __name__忽略另一个文件，然后UpdatePage不存在，引发异常并导致崩溃。
另一个问题与您正在编辑生成的文件有关，pyuic并且正如这些文件标题中的警告明确指出的那样，除非您真的知道自己在做什么，否则不应修改这些文件，并且其中之一阻止这种做法（这被认为是不好的做法）的许多原因是它通常会导致对对象结构的误解，就像您的情况一样。这些文件仅用于导入，很少有特殊情况可以考虑对其进行修改，但一般规则是，如果您知道自己在做什么，就不会这样做。
pyuic 构建的 UI 的任何实现都应该通过继承其相应的 QWidget（在您的情况下为 QMainWindow）并使用生成的 UI 类在其上构建 ui 来完成。这不仅简化和澄清了事情，而且还允许正确访问实例方法，例如close()，而不是尝试以错误的方式做事（如访问全局）。我不会深入探讨这一切是如何工作的，但概念是使用您的方法，self在所有这些方法中，都指的是 的实例Ui_UpdatePage，而在正确的方法中，它指的是实际的主窗口对象。
所以，简而言之，用 pyuic 重新生成你的 ui 文件（在下面的摘录中，我生成了文件update_ui.py和user_ui.py，然后将方法实现到正确的子类：
update_window.py：
from PyQt5 import QtCore, QtGui, QtWidgets
from update_ui import Ui_UpdatePage
class UpdatePage(QtWidgets.QMainWindow, Ui_UpdatePage):
def __init__(self):
super().__init__()
self.setupUi(self)
def save_data (self):
# ...
def exit_popup_message (self):
# ...
if x == msg.Yes:
self.close()
user_info.py：
from PyQt5 import QtCore, QtGui, QtWidgets
from update_window import UpdatePage
from user_ui import Ui_User_Info
class UserInfo(QtWidgets.QMainWindow, Ui_User_Info):
def __init__(self):
super().__init__()
self.setupUi(self)
def exit_popup_message(self):
# ...
if x == msg.Yes:
self.close()
def update_button(self):
self.window = UpdatePage()
self.window.show()
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
userInfo = UserInfo()
userInfo.show()
sys.exit(app.exec_())
